Gib key puller.

Hi All,
Anyone got a puller for the flywheel key on a R&H PT (1 1/4" crankshaft) that they're not using?
I checked Stationary engine spares and fleabay.

Any help would be much appreciated.

Cheers,
Mike

make a shallow wedge to place between the flywheel and key head then tap the wedge to release the key.

Thanks, you make it sound so easy.

When you say "tap" it's more like belt it with a club hammer (in a controlled manner of course).

Mike.

If its that tight to use a club hammer it wasn't fitted properly.

Who knows what had happened in it's 82 year lifetime.
I suppose I'll be a bit (more) stubborn when I get to that age.

Mike.

Hi All,
Don't worry about the puller, I've made one now.

Cheers, Mike.

Good news. Pictures please ?

Paul,

Had to resort to drilling the decapitated old key.
Fortunately the belt pulley on the PT is bolted through the flywheel so I made an adaptor plate and used my hydraulic three leg puller to draw it off, key and all.



It put up little resistance.

Mike.

Nice work.

Check out VilliersParts & also Villiersservices , I,ve seen one of a sort online somewhere , you might have to print a picture of one , then get it made to scale to fit your engine . They look much like a setscrewed flywheel puller .
Decades ago when I first had to get my old Dad,s Villiers going on a bale elevator it had a gibhead key holding a cast iron flat-belt pulley on the 6;1 reduction gearbox output shaft , he & Walt had ran it to destruction trying to get hay bales off trailers before it rained , & I needed the pulley for the next engine that I,d built from several boxes of bits , the only way I could get that key out was to drain the reduction box oil right out , then very carefully gas torch warm up , not get red hot , the centre hub of the pulley , this expanded the hub off the key just enough to be able to tap the pulley hub further down the shaft slightly with a stout steel tube & hammer which relieved it,s grip on the key , which I then carefully pulled out with pliers , DEAD STRAIGHT , don,t bend it or it will promptly snap off in the groove . Let it cool down , apply the great persuader ( Plus Gas ) & the pulley pulled & twisted off by hand .
A few years ago I got to know a very skilful guy who had been apprenticed at Alfred Herbert,s in Coventry , there wasn,t much he couldn,t handle , & he was a proffessional engineer & machinist , sometimes he would look at me in speechless disbelief at the capers & solutions I,d done or found , then tell me a vastly simpler way of achieving the same end in much shorter time , find a guy like this , my mate is now dead , a great guy gone & massive skills lost . His Son continues .
